Answer:
Step-by-step explanation:
Bricks Wall
l=25 cm l=6 m =600 cm
b=12.5 cm b=50 cm
h=7.5 cm h=5 m =500 cm
volume of wall=l x b x h
=600 x 50 x 500
=15000000 cubic cm
volume of mixture =1/20 x 15000000
=750000 cubic cm
volume left =15000000 - 750000
=14250000 cubic cm
required brick =14250000/25 x 12.5 x 7.5
=6080 bricks
